i keep tea in them. i have about 8 pu-erh cakes without jars right now. when i brake up a cake i put it in the jar. they have loose fit lids. i will be using them all unless someone asks for one.
the water jars are still drying on the shelf about 3 more days till i bisque fire again. then i will glaze the water jars. 5 of them 1 has a S crack in the bottom which i will keep to put Melon tea in from the 2 kilo baby i been drinking.
Let me suggest that you photograph your things out of direct sunlight. Like Cory, I was a pro photographer for many years. You want softer light on your pieces so there is less harsh glare and contrast. It's not easy photographing reflective surfaces. It is important to get close to the objects so details can be seen by the viewer. Hope this helps you.
